Because transportation accounts for about 72% of U.S. petroleum consumption, reducing our dependence on petroleum-based fuels in this sector supports our economy and our energy security.

Increased economic and energy security aren’t the only benefits of reducing petroleum use in transportation. Gasoline- and diesel-powered vehicles are major sources of greenhouse gases, smog-forming compounds, particulate matter, and other air pollutants. Widespread use of alternative fuels and advanced vehicles could greatly reduce the emissions that impact our air quality and public health.
